Drain the beans and add; mix well. Simmer over very low heat until meats are tender, about 11/2 hours (make sure it never boils, or the meat will become tough). When meats are tender, strain broth from the Dutch oven and refrigerate overnight. Remove grease that rises to surface on next day.
Day 2 or 3: Let the mixture come to room temp. Cut the bacon slices into 1/2-inch squares and sauté until crisp; add to Dutch oven. Sauté garlic sausages, cut into 1-inch pieces and add them to Dutch oven, along with enough broth to just cover the beans and meat. Simmer very gently, for 1 hour, or until beans are tender and flavors are combined. Every few minutes, distribute a little of the finely minced garlic through the stew. Add additional chicken stock or water as needed; the sauce around the beans and meat should be ample and medium-thick, neither pasty nor soupy.
Add brandy, season with salt and pepper to taste and bring to a boil on top of the stove. Reduce heat to low and simmer 5 more minutes (add more liquid if necessary to make a medium-rich sauce). Divide among plates, sprinkle with parsley and serve with crusty bread.
